Asian Hornets Sighted in UK as Public Urged to Act
The invasive Asian hornet, a significant threat to honeybees and other pollinators, has been increasingly spotted across the UK, prompting urgent calls for public vigilance. Known scientifically as Vespa velutina, the Asian hornet is notorious for its predatory behavior towards bees, posing a severe risk to the delicate balance of our ecosystems.
The Threat of the Asian Hornet
Asian hornets are adept hunters, capable of catching and dismembering honeybees with alarming efficiency. They typically wait outside hives, capturing bees as they enter or exit, then feed their thoraxes to their young. This behavior has caused considerable alarm in France, where the hornet population has already established itself, leading to significant losses in bee colonies.
Rising Numbers and Immediate Action
According to the British Beekeepers Association, a single Asian hornet can consume 30 to 50 honeybees a day. The number of sightings in the UK has surged, with 57 sightings reported in 2023 alone—more than double the total of the previous seven years combined. This increase has raised fears that the Asian hornet is on the verge of establishing a permanent presence in the country.
The Department for Environment, Food & Rural Affairs (Defra) has confirmed that queen hornets found in East Sussex are offspring from a nest destroyed last November, indicating that the hornets have indeed survived the UK winter. This survival suggests a growing and breeding population, emphasizing the need for immediate action.
Public Involvement and Reporting
Defra’s chief plant and bee health officer, Professor Nicola Spence, has called for public vigilance: "By ensuring we are alerted to possible sightings as early as possible, the public can help us take swift and effective action to stamp out the threat posed by Asian hornets."
The public is advised to report any sightings through the Asian Hornet app or the online reporting system. Identifying features of the Asian hornet include a very dark body, a wide orange stripe on the fourth abdomen section, and yellow-tipped legs.
Expert Insights and Ongoing Efforts
Dr. Gavin Broad from the Natural History Museum provides tips on spotting these invasive insects: "They're much darker than any British hornets and social wasps. They look almost black with a distinctive color pattern."
Asian hornet queens can reach up to 3 cm in length, and workers around 2.5 cm. If you spot a hornet or a nest, do not disturb it but report it immediately. The UK has seen a record number of 72 nests destroyed in the past year, highlighting the effectiveness of these reports.
Long-Term Implications
The potential establishment of the Asian hornet in the UK poses a significant risk to local pollinators and ecosystems. Ian Campbell of the British Beekeepers Association warns of the dramatic consequences: "They like social insects, such as honeybees, because social insects congregate in groups—like an all-you-can-eat buffet for the hornet."
Efforts to control the Asian hornet population are critical to protecting the UK's native bees and maintaining ecological balance. The ongoing surveillance and reporting by the public play a vital role in these conservation efforts.
Conclusion
The Asian hornet's presence in the UK underscores the importance of public awareness and proactive measures. By staying vigilant and reporting sightings, we can help protect our pollinators and preserve the health of our ecosystems.
